I believe the basis for the comment regarding it being "a clone" was based on the fact it will only work on a early image, this is I believe a common problem with clone receivers. Please do not take any offence, it was a justified question based on the information you gave. The clones are very good and quite hard to spot for anyone.
I do hope you get the receiver working to its full capabilities, as I said earlier, a ftp client like Filezilla will help you to access the vu without the need for any other client.
